"Father of the Amero" Herbert Grubel speaks about a common North American currency

This is a scene from a new documentary I am producing by director Bryan Law.
The Father of the Amero, Professor Herbert Grubel speaks about his 1999 publication, "The Case for the Amero" and talks about the economic benefits of having a common North American currency. He also speaks about a necessary catalyzing event required, in order to have political change which could bring about a monetary union.
